TAP FOR BARRELS.

SPECIFICATION forming part of Letters Patent No. 243,211, dated June 21,1881.

Application filed March 5, 1881. (N 0 model.)

To all whom it may concern Be it known that I, JOHN J. CHRISTIAN, acitizen of the United States, residing at Youkers, in the county ofWestchester and State of New York, have invented new and usefulImprovementsin Taps forBarrels, 50., of which the following is aspecification.

This invention relates to tapping devices for barrels or other vessels,adapted to automatically close the tap-hole when the faucet is removed,and to be dislodged by the fauce when it is inserted.

This invention is illustrated in the accompanying drawings, in whichFigure 1. represents alongitudiual central section. Fig. 2 is a frontview. Fig. 3 is a detail view, herein after explained.

Similar letters indicate corresponding parts.

The letter A designates a plug cast, or-otherwise formed,of brass orother metal, to an annular or cylindrical shape. On the outer end ofthis plug are ears B, which are integral therewitluand in these cars areformed screwholes, so that if the plug is inserted into the tap-hole ofa barrel or other vessel it can be readily secured in position throughthe medium of the ears. The object of this means of securing the plug Ais to leave the tap-hole plain, or avoid any special preparation thereoffor the reception of the plug. The inner diameter of the plug A iscontracted on its outer portion to form a seat, 0, for a valve, D, whichis fixed to a stem, E, sliding in a guide formed by a cap, F, at theinner end of the plug, and which is subjected to the action of a spiralspring, Gr, having a tendency to force it against the seat. That portionof the plug A inward from the valve'seat O is perforated with numerousholes 1', through which the liquid passes from the vessel to the faucetwhen the faucet is opened, while that portion of the plug outward fromthe valveseat is screwthreaded internally, as at 0, to a pitchcorresponding with the thread on the faucet. The valve-seat G isbeveled, and the valve D is a frustum of a cone, thus being adapted tothe seat. The valve-stem E projects in an inner direction from the valveD through the cap F, and opposite to this stem, so as to project in anouter direction from the valve, is a breast or protuberance, s, whichconstitutes a point of contact for the faucetthat is to say, when a.faucet is screwed into the plug A it strikes the breast 8, thus forcingthe valve back from its seat against the action of the spring G andopening the vessel to the faucet, and by this means the friction betweenthe inner end of the faucet and the valve is reduced to a minimum. Thecap F is secured to the plug A by means of a screw-thread, and it isremoved when it is desired to put the valve into its place. The spiralvalve-spring G is arranged on the stem D, and it is compressed by thecap F against the valve, so as to exert the required action thereon.

By the construction above described I obtain a tap capable of closingthe tap-hole to which it maybe applied automatically, when the faucet isremoved, and one which involves the least labor or expense in itsconstruction.

lam aware that a cylindrical tap for barrels has been provided withperforated ears for attaching it to the vessel by ordinary wood-.s'crews; but such, broadly, I do not claim.

I am also aware that a tap for barrels has been composed of a threadedhollow bushing perforated at its inner portion and containing an in\vardly-projecting guide-shoulder for a perforated sliding tube, saidtube hav ing a collar at its rear end, which is acted on by a coiledspring, and the forward end of the perforated tube being arranged to bepushed inward by the insertion of the faucet into the bushing, so as topermit the liquid to pass through the perforations of the bushing andflow through the perforations in the sliding tube into the faucet; butneither do I claim this construction of tap.

What I claim as new, and desire to secure by Letters Patent, is

A tap for barrels consisting of the cylindrical plug A, havingperforated ears B, the inner diameter of theplug being contracted I intothe beveled valve-scat C, and having theperforations i i and theinterior screw-thread, 0, the cap F, secured to the. inner end of theplug and formed with the guide-opening for the valve-stem, and thespring-actuated beveled valve D, having the solid front protuberance, s,and rear stem, E, attached to the valve, and projecting through theguide-open-. ingin the cap F, the whole being constructed and arrangedas herein shown and described. In testimony whereof I have hereunto setmy hand and seal in the presence of two subscribing witnesses.
